Examining social withdrawal in relation to academic enablers in students with and without cognitive disengagement syndrome.

Students' social behaviors are associated with academic enablers and academic outcomes. However, social withdrawal, a key correlate of youth with cognitive disengagement syndrome (CDS), has not been examined in relation to academic enablers. In this cross-sectional study, we examined associations between teacher-reported social withdrawal and academic enablers, and also whether associations differed for students with or without teacher-reported elevations in CDS.

Threat and Deprivation as Distinct Predictors of Posttraumatic Stress and Depression Symptoms in First and Second Generation Latinx Youth.

Recent adverse childhood experiences (ACEs) scholarship emphasizes that differing ACEs affect the onset and course of psychopathology, and that sociopolitical context contributes to ACEs experienced by marginalized youth. Guided by the Immigration-Related Adverse Childhood Experiences Model, we explored the associations between different ACEs-immigration enforcement fear and perceived economic hardship-on posttraumatic stress disorder (PTSD) and depression among first and second-generation Latinx youth in immigrant families. Participants (n=306) included students from 11 high schools in two states (58% female; 25% aged 17 or older).

Retrospective Report of Academic Motivation Among College Students With Elevated ADHD Symptoms.

Objective: Children with ADHD exhibit deficits in academic motivation compared to their peers. Yet conceptualizations of motivation according to prominent motivation theories connected to achievement have not been studied in college-bound youth with ADHD symptoms.

Method: This study examined motivation according to these theories, differences in motivation by ADHD symptoms, and how the cross-sectional association between motivation and achievement varies by ADHD symptoms.

Impairment's Role in the Pathway From Externalizing Psychopathology to Depressive Symptoms in Adolescents With ADHD.

Objective: This study examined the role of academic, social, and family impairment in the pathway from externalizing psychopathology to depression among young adolescents with ADHD in a multiple mediation model.

Method: The sample included adolescents with ADHD enrolled in an intervention trial. Parent ratings of externalizing psychopathology were measured at eligibility assessment, adolescent self-reported depressive symptoms were measured at eligibility and at the end of treatment, and parent-rated impairment was measured in the middle of treatment.

Discrimination and PTSD among Latinx immigrant youth: The moderating effects of gender.

Objective: Discrimination is a minority-related stressor that contributes to mental health disparities between Latinx youth and their racial/ethnic peers. Discrimination activates the body's stress response system, resulting in a higher allostatic load that can cause mental health problems such as PTSD. We explored 1) the relation between perceived discrimination and PTSD symptoms among Latinx immigrant youth, and 2) how gender moderates this relation.

Uncertainty About the Size of the Unauthorized Foreign-Born Population in the United States.

One of the most common methods for estimating the U.S. unauthorized foreign-born population is the residual method.

Birds of a Feather: An Examination of ADHD Symptoms and Associated Concerns in Partners of Adults with ADHD.

Objective: Adults often select romantic partners who behave like they do (i.e. assortative mating).

Immigration Enforcement Fear and Anxiety in Latinx High School Students: The Indirect Effect of Perceived Discrimination.

Purpose: Immigration enforcement policies and negative rhetoric about immigrants harm the psychological well-being of Latinx youth in immigrant families, particularly those who are most vulnerable because of their own or their loved ones' legal status. According to the Integrative Model for the Study of Developmental Competencies among Minority Children, discrimination may be one pathway to explain how vulnerability to restrictive immigration policies affects Latinx youth mental health.

Methods: We collected data from 306 Latinx high school students from immigrant families in Harris County, Texas, and Rhode Island to (1) determine the direct effect of immigration enforcement fear (a proxy for the social position of vulnerable legal status) on adolescents' anxiety; (2) explore the effect of immigration enforcement fear on anxiety through the pathway of perceived discrimination; and (3) test whether the different enforcement climates in the two study sites moderate these pathways.

Traube-Hering waves are formed by interaction of respiratory sinus arrhythmia and pulse pressure modulation in healthy men.

Excessive blood pressure variation is linked to the development of hypertension and other diseases. This study assesses the relative role of respiratory sinus arrhythmia (RSA) and pulse pressure (PP) on the amplitude and timing of blood pressure variability with respiration [Traube-Hering (TH) waves]. We analyzed respiratory, electrocardiogram, and blood pressure traces from healthy, supine male subjects ( = 10, mean age = 26.

The interplay between cerebellum and basal ganglia in motor adaptation: A modeling study.

Motor adaptation to perturbations is provided by learning mechanisms operating in the cerebellum and basal ganglia. The cerebellum normally performs motor adaptation through supervised learning using information about movement error provided by visual feedback. However, if visual feedback is critically distorted, the system may disengage cerebellar error-based learning and switch to reinforcement learning mechanisms mediated by basal ganglia.

The Functional Role of Striatal Cholinergic Interneurons in Reinforcement Learning From Computational Perspective.

In this study, we explore the functional role of striatal cholinergic interneurons, hereinafter referred to as tonically active neurons (TANs), via computational modeling; specifically, we investigate the mechanistic relationship between TAN activity and dopamine variations and how changes in this relationship affect reinforcement learning in the striatum. TANs pause their tonic firing activity after excitatory stimuli from thalamic and cortical neurons in response to a sensory event or reward information. During the pause striatal dopamine concentration excursions are observed.

Commentary on "The number of undocumented immigrants in the United States: Estimates based on demographic modeling with data from 1990-2016".

"The number of undocumented immigrants in the United States: Estimates based on demographic modeling with data from 1990-2016" by Fazel-Zarandi, Feinstein and Kaplan presents strikingly higher estimates of the unauthorized immigrant population than established estimates using the residual method. Fazel-Zarandi et. al.

Reward Based Motor Adaptation Mediated by Basal Ganglia.

It is widely accepted that the basal ganglia (BG) play a key role in action selection and reinforcement learning. However, despite considerable number of studies, the BG architecture and function are not completely understood. Action selection and reinforcement learning are facilitated by the activity of dopaminergic neurons, which encode reward prediction errors when reward outcomes are higher or lower than expected.

Sensitive subjects: research choices and presentational challenges in studying immigrant children and families.

We write from our own experience as researchers on the integration of immigrants and their children, describing several ethical and research considerations that we addressed. In one study we examined the use of public benefits among immigrant families. This study posed issues regarding the selection of which "benefits" should be considered as "welfare"; how to construct comparison groups of immigrants versus natives; and the political sensitivities in reporting widely high use rates of certain benefits, particularly Medicaid.

Changes in sexual risk behavior as young men transition to adulthood.

Context: Understanding how young men's sexual risk behaviors change during the transition from adolescence to early adulthood is important for the design and evaluation of effective strategies to reduce the transmission of HIV and other STDs.

Methods: Data from three waves of the National Survey of Adolescent Males (1988, 1991 and 1995) were used to categorize 1,880 respondents into clusters according to sexual risk behaviors. Univariate and bivariate analyses were conducted to assess associations between clusters and rates of self-reported STD diagnoses and positive chlamydia tests.

Food security during infancy: implications for attachment and mental proficiency in toddlerhood.

Objective: This study examined the associations between household food security (access to sufficient, safe, and nutritious food) during infancy and attachment and mental proficiency in toddlerhood.

Methods: Data from a longitudinal nationally representative sample of infants and toddlers (n = 8944) from the Early Childhood Longitudinal Study-9-month (2001-2002) and 24-month (2003-2004) surveys were used. Structural equation modeling was used to examine the direct and indirect associations between food insecurity at 9 months, and attachment and mental proficiency at 24 months.

Diving deaths - use words wisely.

Dear Editor, I have just been reading the article by Andrew McClelland in the last issue and am suffering from the horrors and sleepless nights! In case report SC 03-01, for example (the healthy [sic] diver with a BMI of 36.5), it is reported "the deceased rapidly found it hard to swim". Was this establishing rigor mortis? The thought of "the deceased panicked and had a knife in his hands" and later, "the deceased was lunging with the knife" brings back to mind some zombie-type horror movies.

Food insecurity works through depression, parenting, and infant feeding to influence overweight and health in toddlers.

We used the Early Childhood Longitudinal Study-Birth Cohort 9- and 24-mo surveys (n = 8693) and Structural Equation Modeling to examine direct and indirect associations between food insecurity and toddlers' overweight (weight for length), physical health, and length for age. There were significant effects of food insecurity on parental depression and parental depression in turn influenced physical health. There were also significant effects of food insecurity on parenting practices, which in turn were significantly associated with infant feeding and subsequently toddlers' overweight.

Team Echo: observations and lessons learned in the recovery phase of the 2004 Asian tsunami.

The 26 December 2004 Tsunami resulted in a death toll of >270,000 persons, making it the most lethal tsunami in recorded history. This article presents performance data observations and the lessons learned by a civilian team dispatched by the Australian government to "provide clinical and surgical functions and to make public health assessments". The team, prepared and equipped for deployment four days after the event, arrived at its destination 13 days after the Tsunami.

A communication tool for cancer patients with pain: the art therapy technique of the body outline.

Objective: The multidimensional aspect of pain suggests the use of multimodal interventions. The Memorial Sloan-Kettering Cancer Center has recently utilized the art therapy modality to help patients communicate the painful side of their illness in such a way that they can feel understood and respected. In this paper we describe a simple innovative art therapy intervention that we have developed within the Art Therapy Service in the Psychiatric Department of Memorial Sloan-Kettering Cancer Center.
